Why Pettit Protect?
Pettit Protect utilizes Mica Shield Technology. Pettit Protect Mica is incorporated into the epoxy resin while in sheet form, where as other competitors use Mica in a ground form. The differences between the types of mica used in epoxy primers is the ratio of the mica particle length to its width. Pettit Protect uses a high aspect ratio mica whereas other competitors use a low aspect ratio mica. The sheets with high aspect ratio Mica are forced to overlay each other creating an impenetrable layer of epoxy.
Pettit Protect high-solids formula saves time and money because it allows for quicker and easier application with fewer coats necessary for effective protection. When compared to competitive products, Pettit Protect’s high-build formula allows for application of heavier coats without it running or sagging while still providing a smooth finish for antifouling paint. Pettit Protect uses less solvent than competition and this reduces solvent smell. Together this results in less labor and less product needed to obtain the Dry Film Thickness (DFT) necessary for the ultimate in protection.
Pettit Protect can be easily applied by brush, roller, or spray. Use a high quality bristle brush or 3/8" nap roller made for epoxy paints. Thinning is generally not required, but in adverse weather conditions, Pettit Protect may be thinned up to 10% with Pettit 97 Epoxy Thinner to ease application. Stir or shake contents thoroughly to remix any settled material. Mix 3 parts Part A with 1 part Part B by volume and stir thoroughly.

What is Pettit Protect Gray High Build Epoxy Barrier Primer Coat used for?
Pettit Protect is a two-part, high-solids epoxy primer designed to reduce water absorption in fiberglass hulls and help prevent osmotic blistering. It also provides corrosion protection for steel, aluminum, and other underwater metals, making it suitable for both commercial and pleasure craft applications.
How many coats of Pettit Protect Epoxy Primer are required?
At least three coats are specified for the general application system. However, the required number depends on the substrate and application. New unblistered fiberglass may use two coats, while severely blistered hulls call for three coats. Each coat provides approximately 4 mils of dry film thickness.
What is the mixing ratio for Pettit Protect Epoxy Primer?
Mix Pettit Protect at a 3:1 ratio by volume, using three parts Part A to one part Part B. Stir both components thoroughly before and after combining them. Allow the mixed material to stand for a 15-minute induction period at 70°F before application.
Can Pettit Protect be used on fiberglass, steel, and aluminum?
Yes. Pettit Protect can be used on fiberglass as a barrier coat and on steel and aluminum for corrosion protection. The product description also provides specific preparation systems for lead, steel, and cast-iron keels. Surface preparation and any required primers vary according to the substrate.
What are the application temperature and coverage for Pettit Protect?
Pettit Protect should be applied at temperatures between 50°F and 90°F. When applied with a 3/8-inch nap roller, the stated coverage is approximately 225 square feet per gallon. It can be applied by brush, roller, airless spray, or conventional spray.
How long should Pettit Protect cure before bottom paint or launching?
Dry times depend on temperature. At 70°F, the coating can be recoated after 3 hours, requires at least 72 hours before launching, and can receive bottom paint after 5–8 hours. If the specified recoat interval is exceeded, the surface should be thoroughly sanded with 80-grit sandpaper before recoating or applying bottom paint.
